饲粮中添加花生秧对伊拉兔肠道菌群的影响
Effects of Diet Supplemented with Peanut Vine on Intestinal Flora of Ira Rabbits
摘要
Abstract
In order to analyze the effects of peanut vine supplementation on intestinal flora of Ira rabbits, sixty male and sixty female growing Ira rabbits were selected in this experiment. All of the healthy rabbits at the age of (35±2) days were randomly divided into 6 groups with 4 replicates per group and 5 rabbits per replicate. Rabbits in the 6 groups were fed pellet feeds which supplemented with 0 ( control group) , 10.0%, 12.5%, 15.0%, 17.5% and 20.0% peanut vine, respectively. The period of trial was 42 d with 7 d of pretrial. After the feeding experiment, the biological information of 16S rDNA V3 to V4 region of cecal microorganisms in rabbits were analyzed by the high through sequencing technology. The results showed as follows: at phylum level, the proportion of Candidatus saccharibacteria in cecal contents in 15.0%, 17.5% and 20.0% groups was significantly decreased ( P＜0.05) , while the proportion of Actinobacteria in 17.5% and 20.0% groups was sig?nificantly decreased compared with the control group ( P＜0.05) ; at genus level, the proportion of ClostridiumⅣ in cecal contents in 17.5% and 20.0% groups was significantly increased compared with the control group ( P＜0.05). Therefore, the diet supplemented with peanut vine can affect the balance of cecum microbial com?munity and change the proportions of some bacteria with important metabolic functions.[ Chinese Journal of Animal Nutrition, 2019, 31(6) :2735?2744]关键词
